[Mpi3-tools] MPI_T session question

Folks,

If an application has multiple sessions and does a PVAR_START on all 
sessions, is the intention that the MPI implementation will keep track 
of each pvar on each of the sessions?  Since when the pvar_start is 
called for each session is different, the values of these variables can 
be different.  So is the MPI implementation expected to replicate these 
variables per session?  Is this true for the read-only ones as well, 
since the start time can be different for each session?
